I'm having a hard time correctly calibrating my JVC RS45 that has 1100 hours. here is the calibration result 1107H_Sep242013_Cinema.pdf 1354k .pdf file

Red is clipping a lot when looking at Clipping Pattern on Spears & Munsil 2nd edition. Previously I was able to see the clipping pattern correctly around 500 hours.

Does this mean that its time for me to change my projector bulb? I've already spend 3 days using several modes (Film, User etc with several color temp settings) and correctly setting contrast and brightness before calibrating. I also warm up the Projector about 1/2 hour to an hour before calibrating.
How do i correctly calibrate it looking at the calibration results.

Here is JVC settings
Mode:Cinema
Contrast:3
Brightness:-6
Color:0
Tint:-2
Color Temp:5500K (I've tried 6000k and 6500k but they tend to be very cool). Could not get white balance correct with other settings.
Gamma: 2.4
Color Space:Wide1
CMD:off
Lens Aperture:-3
HDMI:Enchanced
Lamp Mode: Normal


Also I want to know how much Luminance Ft/L from Chrompure calcualtion results. In Gamma it shows % Output before and after.

1. Use the JVC's own custom white balance controls to achieve a good result at 100%. This may require that you turn down contrast a little. It looks like you are running out of red and gamma is falling at the high end. This is a classic sign of overdriving the bulb. Open up the aperture to compensate for loss of light output.

2. You can see 100% luminance in any number of places, including on the report you attached. 100% in Grayscale, in White Balance, Contrast, and in Raw Data.

3. Gamma is 0 at black and full white by definition.

  1. So I need to change the Gain settings in Color Temps but I've read not to change any offset but only Gain except the Green controls. Is this correct? Do I have to re-run the Auto-cal after making adjustments to white balance.
  2. Or Can I simply go to Lumagen Gray Scale menu and adjust the Red balance at 90% and 100% after opening up the aperture to 0 which is max. Since that's where the error is at.
  3. What are units of luminance setting in various area? All I'm interested is in knowing if I have the required 14 FL output. What setting do I look for that?
  4. Is see this in After Color calibration setting Y = 10.115.
    Color x y Y dE
    White 0.315 0.333 10.115 2.0
  5. What does this indicate in Gamma report?
    Input Pre Post
    0 % 0.00 0.00
    10 % 0.09 0.09
    20 % 0.49 0.46
    30 % 1.38 1.17
    40 % 2.74 2.18
    50 % 4.58 3.71
    60 % 6.69 5.82
    70 % 9.67 8.43

1. Yes. Then run auto-cal again.
2. No. Make the change at 100% using the JVC controls.
3. ft-L is a deprecated system. The default in CP is cd/m2. 48 (which equals 14 ft-L) is the target value. You are getting 18.58. Any place in the application that shows 100% output (there are many) gives the value you are looking for.
4. It indicates cd/m2.

Hi,
Because you are using HDMI on enhanced,your contrast is to low...usually the better setting is from 7-10,many are using until 14.In this way you don't lose precious light from your projector.
You can use also HDMI on standard with the default settings-contrast,brightness,color and tint all to 0.
Also try to start from USER mode with color temp at 6000-6500-7000K...in my case 7000 was best ...but i have RS46

Lumagen Radiance 20XX Series (2021, 2022, 2041, 2042) New 092013 Firmware Update

Release Notes

Fixes an audio issue which in some setups could result in missing channels for multi-channel PCM. Fix for audio only on output1 when using 4K video on output2. This could result in a couple of problems--no audio from output 1 depending on the AVR and occasional stutter on the output 2 used for video if the AVR was having an issue.

I thought HDMI std will clip white level above 235 and black level below 16. That's why i always use Enhanced. Let me know if i'm wrong

What values are you using for these inputs Color Space, CMD, Lens Aperture?
Are you using any offsets or gain for Color Temps?
Thanks for the suggestions.

Here are my new calibration results with these inputs

post #4783 of 5345
Yes,it will clip the signal above 235,but it is not so important because you don't find many movies to benefit from that,it is more important not to lose to much light from your projector.Regarding black level is OK if you resolve the signal at 17-18.
In my case i use color space on standard,but in your RS45 i think that WIDE1 is better to deal with, if you have an
external processor as Lumagen. CMD is Off.and lens aperture is at -11.
I am using only gain for color temp at 100%
Are you using an external processor?with auto cal?
Sorry for my English

I'm using CP's 125-point autocal on my new JVC 4810+Lumagen for the first time. I couldn't find a preset gamut that didn't have green & cyan undersaturated, but I went with the closest I could find. The results are not good...greyscale got much worse after autocal.

JVC 20130929 CalibrationSummaryDetailedWithAdvGamut.pdf 2485k .pdf file

I assume the problem is that the gamma was so far off to begin? I didn't attempt to adjust that beforehand. The only PJ settings I adjusted were the picture mode (Cinema, which measured a little better on the primaries than Film), then the usual contrast/brightness/color/tint, then RGB gain for 100% white.

Any suggestions?
post #4785 of 5345
Although full auto calibration should work just fine, I think you will find that the best results have been obtained by doing the best grayscale and gamma possible manually, then just running the 125point cube gamut cal automatically. This is especially true if you wanted to try tailoring the gamma at the low end, to get better shadow detail for instance.
If your gamma was really bad to start with, again manual cal might give better results.
I'm sure that Tom will chime in with some good advice, he always does.
Regards, Mike.

This is strange. I haven't seen this problem, which begins at 60% on down. Above that it is fine. Do you have the latest build of CP?

If you want me to troubleshoot, then please copy/paste the data in the activity window into an e-mail and send it to ChromaPure support. One general comment: If your average dE is 1.2 before running auto-cal, I would uncheck grayscale and just run auto-cal on color. After auto-cal has finished, in your case I would also adjust the Gamma value in the signal generator toolbar to about 1.05 to raise your gamma across the board. BTW, setting the gamma in the JVC to 2.4 before calibration will help this as well.

What color space is it set at? You should use Wide 1. Otherwise, you will not be able to get better results with the undersaturated green and cyan.

Because you have unlimited time and flexibility, you can always get better results with a careful manual calibration. However, auto-cal should reliably get your average grayscale dE below 2. Any errors below that are invisible and are not really worth spending time on.

Doing a manual gamma calibration at 5% is desirable for the reason you mention.

Thanks Tom; I'll try some of your suggestions over the next few days. My Chromapure is the latest build as of perhaps 2 weeks ago.

There's still a few things I'm confused about:

1. You say to adjust the gamma value in the signal generator toolbar after autocal. I don't understand the purpose of this change. The calibration is done; what will changing the signal generator at that time accomplish?

2. In the big table at the end of my report, there are several lines where the saturation is off by 5,000% or more. I assume this was some kind of measurement error. But on those same lines, the dE is very small. Does that make any sense?

3. Does the Color Checker report require Excel? When I try to create a report it wants to open a CSV file and Windows pops up some dialog box asking me if I want to buy MS Office.

FYI, the first time I tried autocal last night, it died after about 10 minutes with an error popup. Something about indexStart out of range. I restarted it, and it completed fine.

My recommendation was to NOT calibrate grayscale at all IF it was already at 1.2 dE. If you do that, then you'll still need to correct gamma post-calibration. If the pre-calibration grayscale is worth adjusting then no extra gamma adjustment is necessary.

No error. These values are for various levels of white. There is no saturation in white, so reported errors end up with enormous values. Just ignore these.

Yes, it does.

Perhaps I'm just being dense but what do you mean by "signal generator toolbar"? I thought you meant some setting within ChromaPure. But now I'm thinking maybe you're referring to the Lumagen's settings?

I can't seem to find any "Wide 1", either in the menus or manual. According to the first post on the 4810 thread, Cinema is the closest, which is what I saw when I measured the different choices yesterday.

It is both: a feature in ChromaPure that controls the Lumagen's settings.

This was the most important new feature released with version 2.4, but enough people have said essentially this that I wondering if most people even know about this.

Maybe the problem is that I have not really settled on a single name for this feature: Manual Control Toolbar or Video Processor Control Toolbar. It is the same thing.

Sorry. On the RS45, which is what I have there are different color spaces Standard, Wide 1, and Wide 2. Standard is close to Rec. 709, but slightly desaturated. Wide 1 is closer to DCI. I guess your model doesn't have this choice.

I did not know about this feature. I adjusted Gray scale using this feature and it made a huge difference in my after calibration. Few days ago i posted having issues getting correct Red balance. Most of my issues are resolved.
There is one issue left at 10% gray scale where the dE is 16 but i'll readjust the calibration using this tool.

I wish I would have know about this feature earlier.
Here is calibration file after manual adjustment.

When calibrating greyscale, I had problem getting it balanced at under ire 20 and over 90 ire. Between 20-80, it was easily calibrated.

In such a case, we sacrifice the ends and get the in between to be balanced?

The is a fairly common experience and you are doing the right thing. The only solution t this is having a true 10-pt white balance control, such as what is offered by the Lumagen or Duo processors.
post #4799 of 5345
Thanks Tom.

So a lumagen processor needs to be permanently installed in the setup? Or is it just a one time calibrating process?
post #4800 of 5345
It needs to be in the setup permanently.
